It's adorable that you think batteries and dual PSUs are something that makes a node more reliable, rather than less reliable.

- zielmicha 7y agoWhat's the point of dual PSU if not reliability?
- retrovm 7y agoI'm not sure what the point is, actually. The variety of things that can go wrong with them is astonishing. For one thing, among many others, BMC cards will power-cap the max clock speed of CPUs when a machine is running on only one PSU, which can cause a degradation that's worse than if the machine had just halted. There are a zillion other edge cases like that.
